Shell Command Unresponsive Exception in android emulator?

Question

i have a script made using monkeyrunner. The script will install an app, make some key preses to the emulator and then uninstall. In the middle of something I get Shell Command Unresponsive Exception and that will ruin my script.

Do you know what have I done wrong to result to this kind of exception. here's the error message

Kind of late for an answer but MonkeyRunner is probably running on top of Google's ddmlib. In ddmlib, all shell commands that are called on a device have a default timeout of 5000ms. If the process doesn't print anything for that 5000ms, the process will be shut down and a ShellCommandUnresponsiveException will be thrown. If your process takes more than 5000ms to run, you may want to optimise your code to avoid having long processing within the time that the shell commands are called. Alternatively, you can check the MonkeyRunner API to see if there's any way of extending the timeout. Or you could simply continuously output to the shell somehow to prevent the timeout from expiring.
